Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract: An inverter, a power unit and a power module applied to the inverter are provided. The power unit includes a first package module, a second package module, and a third package module, each including two switch transistors that are complementary to each other. Since the first package module and the second package module are arranged in one half of the inner space of the power unit, and the third package module is arranged in the other half of the inner space of the power unit, the control terminal of each of the three package modules is arranged on a side of the half for arranging the package module that is away from the other half. Thus, the power unit can adopt a small-sized packaging structure without changing a layout of driver boards, thereby reducing the cost of the power unit and the inverter.

Abstract: Embodiments provide image display systems and methods for one or more camera calibration using a two-sided diffractive optical element (DOE). More specifically, embodiments are directed to determining intrinsic parameters of one or more cameras using a single image obtained using a two-sided DOE. The two-sided DOE has a first pattern on a first surface and a second pattern on a second surface. Each of the first and second patterns may be formed by repeating sub-patterns that are lined when tiled on each surface. The patterns on the two-sided DOE are formed such that the brightness of the central intensity peak on the image of the image pattern formed by the DOE is reduced to a predetermined amount.
